Data Analysis

The Lab VIEW analysis VIs offer a powerful and comprehensive set of analysis routines for processing acquired data. These VIs give you complete flexibility to develop applications in areas ranging from statistical process control to digital signal processing (DSP). The, following sections list the analysis functions you can perform with these VIs. For additional information, choose the Investigate the Lab VIEW Analysis Libraries option when you launch the Lab VIEW Demo program.
